I would consider being mainstream, at least to your average person in Britain as the bulk of family-friendly toku being on TV in a normal time slot like either Doctor Who or children's slots and the adult toku just overnight or something the same as Japan and unfortunately, there probably will always be some people that ''just don't get it''. But although I can't speak for the US, I think both the UK and Japan are more just a 50/50 situation than like everyone has fast internet, whereas if you're talking about countries with fast internet I would have thought Estonia or South Korea or maybe somewhere in Scandinavia would be more of an obvious choice tbh!
